Sophie, Countess of Wessex, is to throw a reception at Buckingham Palace on November 18 to celebrate Doctor Who’s 50th anniversary.

The Countess, who is a fan of the hit TV series, is expected to meet cast members past and present, just days before the beloved British show marks the milestone on November 23.

Sophie will honour Doctor Who with a reception at Buckingham Palace.

Sophie is likely to meet former doctors Matt Smith and David Tennant as she hosts the royal reception at the London palace.

An official list of guests, which will include crew members, will be released nearer the time.

Earlier this year, Sophie’s brother-in-law Prince Charles and the Duchess of Cornwall visited the Doctor Who studios at Roath Lock, Cardiff, on their summer tour of Wales.

During the visit, Charles had wife Camilla and cast members in fits of laughter as he impersonated a Dalek.

Speaking after the visit, Steven Moffat, the show’s head writer, revealed he would love the Prince of Wales to guest star in the family show.

“Prince Charles’s attempts at being a Dalek was great,” he told BBC News. “There would be a part in the show for him if he wanted it.”

Doctor Who has often featured and referenced Buckingham Palace, with the Doctor revealing he had been given approval by The Queen to park the Tardis in the Palace’s grounds in the episode Planet of the Dead.

Original producer Verity Lambert was honoured by The Queen with an OBE in the 2002 New Year Honours List for services to film and TV production, while the man behind the show’s revival Russell T Davies received an OBE in the 2008 Birthday Honours List for services to drama.
